Abstract
A biosensor, a measuring instrument for biosensor, and a method of quantifying a substrate contained in specimen liquid to reduce a measurement error by the biosensor; a biosensor, comprising at least a pair of electrodes formed on an insulation substrate; a measuring instrument, comprising a supporting part for detachably supporting the biosensor, a plurality of connection terminals electrically connected to the electrodes, and a drive power supply for applying a voltage to the electrodes through the connection terminals; wherein the biosensor is inserted into the measuring instrument, either one of the electrodes of the biosensor is connected to first and second connection terminals fined to the measuring instrument only when the biosensor is inserted into the support part of the measuring instrument in a specified direction and has an electrode structure to allow the first connection terminal to conduct with the second connection terminal when a voltage is applied by the drive power supply.
